My Bridgestone has made it to Karl's so we can custom fit the pipes. The only good thing about this is it's out of my garage for a while. Cause I think it's gonna be a while for those things.
My cb350. I'm getting pretty pissed off about this at this point. Thing was running great before my crash at Frontier Land a couple of years ago. Since then it's been awful. At that time I wanted to put in one of Megacycle's needle bearing kits for the camshaft. So the engine got it's normal winter teardown and put that in along with checking everything else out. Nothing wrong just a general check things and put it back together. What's happening is the camchain is rubbing along the side of the slipper cam chain tensioner. Not really sure at this point what could be causing it. A few weeks ago we tore down the engine, for like the fourth time, and found that the pin that the tensioner pivots on was eating itself into the engine case. And on one side more than the other so it would allow the tensioner to be tilted to one side, i.e. not perpendicular to the crankshaft nor parallel to the direction of the chain. Not sure why but we spent a lot of time and money to fix the problem. We reamed the spot where this pin sits so it would accept a 14mm wrist pin. We then opened up the pivot on the tensioner to ride on the wrist pin. Finally finshed putting the thing together last night, of course Mid-Ohio is this week so no big hurry. Put gas in it pushed it down the driveway to start it around 11:00 PM and within 3 minutes of warming up the same noise was back. The chain must be riding along the side of the tensioner once more.
So now I don't think the wrist pin could have eaten in to the case in that amount of time to cause the tensioner to tilt once more. So now I'm at a loss. When the engine was apart the Megacycle bearing kit was triple checked to be sure it was parallel, so it would not allow the camshaft to be un-parallel from the crankshaft. The crank itself was triple checked to ensure the bearings looked, felt and measured fine on a side to side and top to bottom runout. The sprockets on both the cam and crank don't appear to be moving. So does anyone have any ideas?
